10m WSPR TX
Yet again I am on 10m WSPR TX (500mW, 100% TX, randomised frequencies). As yet, no spots received today.
Optical DXing
Since my 2013 stroke I have not felt fit enough to do field work. I really miss my 481THz over the horizon NLOS (non line of sight) optical work.
The results back in 2013 suggested much further would have been possible NLOS. All the gear was home made and the experiments were fun. Sadly I am just too wobbly these days.
It would be good to try infra-red frequencies. What amazed me was the total lack of a visible signal, yet perfect decode using QRSS3 on the PC on a very non line of sight path over the horizon.

6m FT8 RX
Since just before breakfast, I have been on 6m FT8 RX. Some people hate this mode and I can quite understand why.
It is not a mode for chatting (unlike SSB, FM and AM) with "quick fire" formulaic QSOs. But it works with quite weak signals and in my condition it means I can monitor what I am spotting whilst doing other things.
On 2m FT8 I can spot DX every day which I just wouldn't believe possible a few months ago. Who needs lifts? With FT8 I can spot DX anyway. Most times when I go on 2m FT8 TX with 2.5W and a big-wheel omni I get spotted over 300km.
So far today (it is now 0844z) just 5 Gs spotted and no sign here yet of 6m Es.
UPDATE 1052z: 10 Gs and one ON spotted so far today. No Es here yet on 6m FT8.
UPDATE 1309z: Now 15 stations in 4 countries. Best DX is SP2DDV (1177km) probably Es.
UPDATE 1923z: As yet, no DX outside Europe and North Africa on 6m FT8 RX here today. Best DX is (again) S01WS (3043km) in Western Sahara. 54 stations in 10 countries so far today on 6m FT8 RX.

Storm Gazing - NOT amateur radio
This weekend we had some of our grandchildren here. One was particularly Interested in the maps showing where storms are currently.

6m FT8 thought why I'm not spotting NA
Perhaps the lack of North Americans being spotted on 6m FT8 is in part due to them being on different frequencies? Most days I monitor 50.313MHz FT8, but I believe different frequencies may be favoured "across the pond". FT8 is less good (I think) than JT65, so maybe that is not helping too. For now, I'll carry on looking at 50.313MHz FT8 RX.
NOTE May 30th 2018: Someone has told me today that 50.313MHz is still the preferred FT8 frequency in the USA.

IARU and threats to VHF and up
Southgate News has an article about the threat to our higher bands written by the IARU Region 1. Personally, I think the threat in the UK and Europe is mainly to our microwave bands. Recently great swathes of lower VHF has been made available to amateurs in Eire and in the UK OFCOM has released 2MHz total at 4m and 2m.

Liverpool Metropolitan Cathedral - NOT amateur radio
My wife told me to watch a TV programme called "Flog It" as it included a piece on Liverpool's catholic cathedral.
When I was at university this had just been finished. Inside it is a sea of colour. Outside it is (perhaps) uninspiring and some call it "Paddy's Wigwam". Inside it feels very calming. I like it.

Human Consciousness - NOT amateur radio
Opinions differ about what happens when we die.
Some say human consciousness just ceases and we know nothing. Those of several religious persuasions say "something" lives on. Perhaps all religions are attempts to make sense of our lives? Honestly, I am not sure.
What I am sure about is our attempts to understand are futile. We are human and fallible.
Logic says we just cease to exist. Maybe.
Several events in the last year have made me less religious: all the evidence points to human cruelty and randomness.
And yet.....

6m FT8 RX only
For a while now, I have been on 6m FT8 RX. Quite a few Es spots around Europe, but nothing further afield as yet apart from a 7X2 on the North African coast.
UPDATE 1324z: 29 unique stations in 7 countries and 2 continents so far today spotted on 6m FT8 RX.
UPDATE 1410z: Now 10 countries spotted.
UPDATE 1900z: Now 27 countries spotted today on 6m FT8 RX.
